To all whom it may conem:

Be it known that I, WILLIAM DALTON, of Schenectady, in the county 'ofSchenectady and State of New York, have invented a certain new anduseful Improvement in Non' Chat-tering Brake -Hange'rs, of which iinprovement the following is a specification. The object of my inventionis to rovide a brake hanger in the use of which t e objectionable noiseordinarily made in the ap lication of the brakes may be avoided, tiliisduetothe excessive wear and lost motion between the brake hanger anditspins resultant upon frequent applications of the brakes, and whichare particularly occasioned in the brake rigging of electric mo'- torcars.

The improvement fully set forth.

-In the accompanying drawing: Figure 1 is a longitudinal central sectionthrough a brake hanger embodying my invention, with the support andbrake head and shoe in eleclaimed is hereinafter vation, and; Fig. 2, aview, in elevation, of the brake hanger, taken at right angles to In thepractice of Iny invention, I provide a hollow or tubular strut, 1,having an inner .up er bearing, 2, so fitted in one of its ends lthatthe strut may turn freelyupon it, and connected to its lower end by anexternal screwthread on the strut which engages a corresponding internalscrew thread on a tubular extension, 3b, of the lower inner bearingwhich surrounds the vThe upper and lower inner bearings are suitablysegmentally recessed to fit, respectively, the surfaces of a suspendingpin, 4, conncted to a support, 5, on a member of the truck frame, 6, andof a brake shoe pin, 7, xed in a brake head, 8, which carries a brakeshoe, 9, of the usual form. Outer bearings, 28L and 3, are fitted on thepins, 4 and 7, res ectively, and the strut and bearings are hel inassembled relation by a strap, 10, which passes around the outerbearings. p

A rod or stem, 11, is fitted in the lower 3, and extends upwardlytherefrom in the strut, and a helical spring, 12, is coiled around saidrod, the lower end of said s' Tingbein inserted in a hole in the inne'uwer bearing, 3, and its upper end being turned inclosin 'strap formingover a rivet or in, 13, and passing free y through longitudinal slots inthe rod, 11, at and near its upper end, the rod being similarly slottedat right angles to allow tlie end of thespring, 12, to be connected tothe rivet, 13. l

In they operation of the appliance, as the end pins and bearin s of thebrake hanger become worn in use, t e resultant lost motion is taken up bthe action of the spring, 1i,v which turns tlriefstrut on the internalscrew of the inner lower bearing, thus increasing the operative lengthof the sti-ut and maintaining the pins and bearing sections in normaloperative relation, thereby preventing the chattering which would beoccasioned by undue looseness of the parts.

take up the lost motion without' clamping the bear-ing sections on thepins sufficiently tight to interfere with the free working of thebrakes.

I claim as my invention cure by Letters Patent: 4

l. In a brake hanger, the combination of end bearing sections recessedto fit en brake hanger pins, a compression member impos ing outivvard`pressure upon said bearing sections, atension member imposing inwardpressure upon said bearing sections, and means for automaticallyincreasing the operative length of the compression member in corresondence with wear of the parts.

2. n a brake hanger, end bearing sections recessed to hanger pins, Ubetween said bearing sections, an inc osing stra bearing sections, andmeans for automatically increasing the operative length of the strut invcorrespondence with wear of the parts.

3. In a brake hanger, the combination of end bearing sections'recessedto fiton brake hanger pins, a rotatable intermediate strut interposedbetween said bearing sections, an

the outerabutments of said earing sections, and means for automaticallyrotating said intermediate strut and thereby increasing its operativelength 1n 'c'oires ondence with wear of the parts.

4. n a brake hanger, the combination of end bearing sections recessed tofit on brake and desire to sefit` on brake fixed in the strut, l,

`The tension of the springiis so adjusted as to enable it. to

the combination of` an intermediate lstrut inter osedsforming the outerabutments of said.

ioo v ends, and having hanger pins, a strut; interposed between thebearing sections, said strutl being fitted to turn freely in a' bearingsection at one 0f its a. screw threaded engage ment with a. bearingsection at its opposite end, andv a heben-1 spring connected at one endto the strut and at the other to the beam 'ingv 'Section having' athreaded coniieeton with the stiut.
